Site Optimisation Site optimisation is written automatically within our code to make the most of latent semantic indexing (LSI) the mathematical technique driving search engine development. The beauty of the system is that once installed, it is completely free to use, and it just gets better as your site grows and the search engines index more of you products. The system is based on giving genuine, relevant information to the person searching. We support this with key word research to further enhance performance and can also provide PayPer Click consultancy and analyse its effectiveness.
